How many degrees of burns are there?

The classification of burns is generally categorized into four degrees, which helps to describe the severity and depth of skin damage.

First-degree burns affect only the outer layer of skin, causing redness and minor pain. Second-degree burns extend into the second layer of skin, leading to blisters and more intense pain. Third-degree burns penetrate through both layers of skin, destroying nerves and resulting in a lack of sensation in the affected area. Fourth-degree burns go beyond the skin to damage underlying tissues such as muscles, tendons, and bones.

Thus, four degrees of burns provide a comprehensive understanding of the potential damage to the skin and underlying structures, making it essential for assessing the proper treatment and management of burn injuries.
